The Last Neighbor - Pluto

If you have more than 3 moons you're a planet in my book, but Pluto is what it is - a wee dwarf planet. It looks huge in the pictures now coming in from NASA's New Horizons spacecraft. (Great links to the mission via KnoxViews, where Randy notes "It will take 16 months to download all the data and images collected by the probe... At 3 billion miles away, it takes 4.5 hours for signals to reach Earth.)

Here's the man who first sighted Pluto in 1930, Clyde Tombaugh, who is actually on-board the New Horizons probe ... well, a portion of Clyde's ashes are on-board. An 11-year old English school girl suggested the name Pluto.There is a human fondness for the wee world.It's also essentially our last neighbor here in this Solar neighborhood, and beyond it we see an infinity of galaxies and neighborhoods - and our little neighborhood appears very small.
